William Martin Boucher (November 10, 1899 – November 10, 1958) was a Canadian professional ice hockey player. Boucher played in the National Hockey League (NHL) with the Hamilton Tigers, Montreal Canadiens, Boston Bruins and New York Americans from 1921 to 1928. With the Canadiens he won the Stanley Cup in 1924. His brothers Bobby, Frank and Georges were also professional ice hockey players and all four were members of Stanley Cup championship teams.

He played in the National Hockey League for the Hamilton Tigers, Montreal Canadiens, Boston Bruins and New York Americans. He also played for the New Haven Eagles and Bronx Tigers of the Canadian-American Hockey League. Boucher signed with the Canadiens in 1921, and scored 17 goals in his rookie season. Boucher scored 24 goals in 24 games in his second season. In his third season, 1923–24 Boucher was placed on a line with rookie Howie Morenz and Aurele Joliat in a high-scoring trio.

Boucher led the Canadiens in scoring, and runner-up in the league. The team defeated defending champion Ottawa in the NHA playoffs and the Calgary Tigers in the Stanley Cup Final. When the team played its first game in the Montreal Forum in November 1924, Boucher scored the first goal in the facility, and the first hat trick. In the 1926–27 season, Boucher was loaned to the Boston Bruins before being traded to the New York Americans, where he finished his NHL career.
